I claim:

1. A mop head comprising a body portion formed of a flat plate of sheet metal, a resilient strap forming a readily separable loop around said body portion, said strap having separated end portions and having a longitudinal depression in the inner face thereof, mop material covering said inner face and means for clamping the separated ends of the strap together whereby the peripheral edge of said body portion, said mop material and the depressed portion of said strap are brought into intimate relationship and clamped together.

2. A mop head comprising a body portion formed of a flat sheet metal plate, a metallic strap having resilient portions and separated end portions thereby forming a readily separable loop around said body portion, said strap being bent longitudinally into angular formation, mop material covering said strap and means associated with said strap for closing said separated ends and contracting the loop whereby the fiat plate, the mop material and the strap at the apex of its angle are clamped together.

3. A mop head comprising a fiat sheet metal plate forming a body portion, a resilient strap surrounding the periphery of said body portion, mopping material mounted on the strap and means for clamping the strap and mopping material to the body portion, said mopping material comprising a loop portion adapted to surround the strap, and inner and outer loop portions depending from said first named loop portion and below the body portion, said outer loop portion being larger in size than said inner loop portion and being adapted to be spread out by said inner loop portion.

- I 4. Amop head comprising a body portion having perforations therethrough near the periphery thereof for receiving a liquid, a metallic strap surrounding the periphery of said body portion, a mop swab held on said strap and means for clamping the strap and mop swab to said body portion, said swab being formed of a plurality of mop cords forming a plurality of rows of loops around the periphery of said body portion, one of said rows being directedupwardly and receiving said strap, an inner row of small loops being arranged below the perforations in said body portion and an outer row of large loops surrounding said inner row of loopsi HARRY HERTZBERG.
